Join us for a paid six-month internship where you'll build products for real startups, scale the platforms behind them, and contribute to open source along the way.
We build with Python, TypeScript and Go, and you'll write all three.
What's required
Proficiency with Python and TypeScript.
Comfortable working in Unix/Linux environments.
Hands-on with agent-first tools like Claude Code, Codex or OpenCode.
An entrepreneurial mindset.
A blog with technical writing (nice to have).
Some exposure to Golang (nice to have).
What you will do
Ship real features with agentic AI workflows, not toy demos.
Build backends in Python with FastAPI, Flask and friends.
Craft frontends with React and Next.JS.
Own the whole ride: develop, test, deploy, repeat.
You will enjoy
🧑💻 Remote-first, with hours that flex around you.
🤝 Senior engineers who make time to mentor you.
🛠️ A modern toolkit, and a say in what we add next
